As with most of this family
this species is very much a predator. Four species
have been described to the genus Cephalosilurus
resident in South America. Three of them have been
introduced for keeping in the aquarium, C.
nigricaudus and C.
fowleri. From their form they are
only little differences from each other. Their trademark
is the big head with the little eyes and short barbles
but with an almost head wide mouth. They are sluggish
animals which hardly move and only lie waiting for
prey. Habitat:Occurs in
pools and in the backwater of rapids and fast streams
with sand, rocks, and decaying wood on the bottom.
Found together with Bryconops caudomaculatus,
Characidium blennoides, Pimelodella cristata,
Leporinus friderici and Astyanax meunieri.
